8/3 cups ------> 2 2/3 cups
2x2x2 = 8
so it would be 8 out of 3. How many times does 3 go into 8 evenly?
2 times and that leaves 2/3 left.
Actually Welcome to the concept of area of sector.
Area of sector = theta/360° * πr^2
==> theta = 62°
hence, area = (62/360)* π*(15)^2
==> Area of sector = 121.67 cm^2
hence Area = 121.67 cm^2
